Mark Wild, who joined HS2 Ltd as chief executive in December, said that a wide-ranging review of the infrastructure project will be published next year.
“The prize is clear. However, the programme is in a very serious situation that requires a fundamental reset to enable it to be delivered to the lowest feasible cost,” he said in the statement. “I am committed to delivering this reset over the coming year to ensure the railway can be brought into service safely and efficiently.”
The remaining part of the line, Phase 1, is set to link London’s Euston to a new station at Birmingham Curzon Street. The project also includes new stations at Old Oak Common, in northwest London, and Birmingham Interchange, near Solihull.
Construction Update
HS2 Ltd reported on Monday that 70 percent of the project’s twin-bore tunnels have been excavated to date. This represents 38 of the 55 miles being built for the railway.Five out of 12 tunnel drives have been completed. The drive for the Northolt Tunnel, in north-west London, was finished on Dec. 19. The company also said it started building 158 out of 227 viaducts and bridges, with 13 percent already finished.
The project employs more than 31,000 people and operates 350 active construction sites along the length of the route.
Multiple systems such as tracks, overhead lines, and power will be installed to transform HS2 into an operational railway once construction is complete.
In the coming year, HS2 is set to complete the 8.4-mile Northolt Tunnel, the second longest on the line. Work will also be completed on both bores of the 3.5-mile Bromford Tunnel, a section of the railway that will enable the trains to enter and exit Birmingham.
Costs and Oversight
The costs associated with the first phase of the HS2 were estimated at £20.5 billion in 2012. Since then the forecast costs have surged up to £56.6 billion.Transport Secretary Heidi Alexander said the government is waiting for the results of an assessment by HS2 Ltd to understand the project’s cost, schedule, and capability.
She said that until Wild concludes this work, the government cannot be confident in the forecast outturn cost of the project.
“We are, therefore, managing HS2 Ltd’s delivery through annual funding and delivery targets for this financial year and next, but with reduced delegation on contingency,” Alexander said. “It will also be necessary to agree longer-term funding for HS2 in the spending review, due to conclude next year.”
Phase 1 of the HS2 is estimated to be completed between 2029 and 2033, with HS2 Ltd aiming for a 2030 completion date.
